Germany November 29, 1935 2 Claims.

According to the purpose of use, usually profiled strips of lead are employed as sealing insertion since lead does not allow moisture to pass through it and also because, owing to its yielding 5 capabilities, it satisfactorily adapts itself to all irregularities and unevennesses of the place being sealed. For example in order to secure glass roofs in a water-tight manner on their framework without the aid of cement, sealing cords or tapes 10 of tarred hemp with lead sheathing are inserted between the glass panes and the said rails or frames.

According to the present invention instead of using the sealing insertions heretofore usual insertions are employed consisting of polyvinyl chloride, after-chlorinated polyvinyl chloride or mixed polymerisates of vinyl chloride and acrylic acid ester.

. The invention is clearly illustrated in the ac- 20 companying drawing, in which:-

Fig. 1 is a vertical section of a sealing insertion embodying the invention, and I Fig. 2 is a cross sectional detail of a slightly modified form of tube. I In Fig.1 of the drawing I represents the supporting rail or frame of the glass roof on to which the glass plates 2 are firmly bolted. Between the said supporting rail or frame and the glass plates thick walled tubes 3 of polyvinyl chloride which are pressed around tarred hemp cords 4 are inserted as sealing cords.

In many cases it is advisable to use in place of the tarred hemp cords paper cords or paper strings 5 in which are embedded readily flexible metal wires 6, (Fig. 2) for the purpose of imparting to the sealing cords that property peculiar to lead strips of adaptation to every shape without spring action. 1

or tape, consisting of an outer sheath comprising 20 a substance selected from the group consisting of polyvinyl chloride, after-chlorinated polyvinyl chloride, and mixed polymerisates of vinyl chloride and acrylic acid ester, and a core of paper string containing at least one inlaid flexible metal 25 wire.
